The Teresa Mei government lost the case in the appeal of the country's Supreme Court for invoking Article 50, after the UK's highest judicial body ruled that the government can not go ahead with the exit process by the European Union without approval of the British Parliament.
The Supreme Court rejected the argument of the government that Teresa Mei can invoke its executive powers known "royal prerogatives" to invoke Article 50 of the Lisbon Treaty and to launch the two-year divorce proceeding.
London says it will implement the decision of the Supreme Court
Britain's chief prosecutor Jeremy Wright said the government would implement the decision of the Supreme Court of the country, according to which the Prime Minister Teresa Mei must secure the approval of parliament before starting the official exit of Britain from the European Union.
"Of course the government is disappointed with the outcome," said Wright outside the Supreme Court. "The government will comply with the court's decision and will do what is necessary to implement it," he said.

The British opposition Labor Party announced today that it will not hinder the process of invoking Article 50 --the legal procedure for the withdrawal from the European Enosi-- after the Supreme Court confirmed that the parliament should vote to approve this procedure.
"The Labour Party respects the result of the referendum and the will of the British people and will not prevent the procedure for invocation of Article 50," he said in a statement representative of the Labour leader Jeremy Kormpin.

Britain can discuss but not validate trade agreements while still EU member
Britain can discuss but not ratified bilateral agreements remain as member of the EU, today said European Commission Vice-President, which will lead the technical negotiations for Brexit.
The statements of France Timmermans raise the prospect of obstacles and delays at Britain's plans to seek trade agreements with the United States and other countries while preparing to leave the Union.
The British prime minister Teresa Mei pledged to begin divorce proceedings in March; although the output time was now in doubt when the Supreme Court ruled that they should first seek the approval of parliament.
"It's a very simple legal status," said Timmermans, first vice president of the European Commission.
"Everyone can talk with everyone, but you can sign a trade agreement with a third country only when you will leave the EU. You can not do before," said Timmermans told reporters.
